Bia sends a weak electrical impulse through the. 6 ways to measure body fat percentage 1.
How Do Our Smart Scales Measure Body Fat Withings
How do body fat measurement scales work. A small unnoticeable electrical current is sent from one foot up one leg and down the other leg. That is to say they send a safe and very low electrical current through the lower half of the body. Fat is a poor conductor of electricity compared to other components of the body such as muscle. When you step on sensors on the scale an imperceptible electrical current passes up one leg across the pelvis and then down the other leg. Body fat scales use bioelectrical impedance analysis bia to estimate the relative percentages of different tissues and substances within the body. Body fat scales use a technology called bioelectrical impedance analysis to measure body fat.
For a more accurate analysis of your body fat you may want to find one of the bia devices that has hand electrodes as well. Bioelectrical impedance analysis has been added to traditional bathroom scales. A basic way to measure body fat percentage is by using a soft tape measure like the kind youd use for. The scales send a harmless electrical current up through your body to read the amount. A skin fold test is done using a tool called calipers to pinch different areas of your body and measure.

These hand to foot bia measurements give more accurate readings notes a review article published in nutrition journal in 2008. For example the us army uses a body fat calculation that simply requires an individuals age height. They run a light electrical current through your body measure the degree of resistance or impedance to the flow of the current then use this information to estimate your body fat percentage 2. Most scales that measure body fat simply place electrodes under the foot panels of the scale.
Most of these types of scales use bioelectrical impedance. Body fat percentage scales use a method known as bioelectrical impedance bia to estimate your body composition. Since the electrical current flows more quickly through water and muscle than bone or fat the scale measures the speed of the current. Body fat percentage data can be helpful at the beginning of a weight loss journey says dr. Available in countless models body fat scales use a technology called bioelectrical impedance to estimate how much body fat you have.
